Each one of these eggs from the underside of a leaf was parasitized by a wasp. Their barrel shape with round fringed caps suggests they might be stink bug eggs. Had a stink bug nymph emerged, the caps would have been neatly opened. Instead, they each have a roundish hole chewed in them. In fact, there’s a parasitoid wasp straggler chewing its way free from the rightmost egg.

I might be seeing things, but you can almost make out the wasp’s body through the transparent egg shell.
